Thanks for reminding me of an old favourite Fred.
Let me put in a plug for "The Duke of Earl", despite it's corruption in Australia as the theme for a shampoo commercial.
And more mainstream, Claptons "Layla", if only for the 5 minute intrumental break - I am never sure which is better, Claptons high guitar or that marvellous pounding piano that sets it all up.
As an interrogative, where does Mr Tambourine Man fit in - rock or folk???
